The objective of this article was to evaluate the effects of glyphosate on the initial development of eucalyptus (Eucalyptus urograndis) after its application on brachiaria (signal) grass plants (Brachiaria decumbens). The ...

We are clarifying how the functional embryo growth occurs in germinating seeds of Solanum lycocarpum A. St.-Hil., a nurse plant with a central role in forest dynamics in the Cerrado (a biodiversity hotspot). For that, we ...

Bemisia tabaci comprises a complex of cryptic species, of which MEAM1 (known as B biotype) and MED (known as Q biotype) are the most invasive and widely distributed ones. In Brazil, MEAM1 was first reported in the 1990s, ...

The objective of this study was to determine if lipid extraction processes alter the isotopic value of δ13C and δ15N of tissues (pectoral muscle, thigh and liver) and eggs and if the use of anticoagulants interferes with ...

Knowing cultivation dynamics of sorghum intercropped with tropical forage for silage production is important both for animal nutrition and for the quality of the food, as well as for the sustainability of the agricultural ...

This study was conducted in order to determine the effect of irrigation regime imposed on development stages over safflower growth components (Carthamus tinctorius L.) in Engenheiro Coelho, SP, Brazil. The work was conducted ...

Urochloa spp. grow vigorously in the dry-season of the tropics, and have been used successfully to provide abundant surface residue as cover crop for no-till soybean (Glycine max). Nitrogen (N) fertilizer application could ...

A suitable N source and an optimal application rate can improve the N-use efficiency of potato (Solanum tuberosum L.) while minimizing N losses, especially when potato is grown in sandy soils. Three experiments were conducted ...

The objective of this study was to evaluate the impacts of irrigation with treated effluent of domestic origin (EET) and different doses of composted sewage sludge (CSS) on soil chemical attributes and heavy metals ...

Since there is no consensus on phosphogypsum (PG) rates to be used in agriculture, a better understanding of its effects on the soil solution is needed. Cotton root growth was evaluated as related to Al and Ca activity in ...

The research aimed to evaluate the performance of herbicides tank mixtures with the Fertiactyl Pos (TM) foliar fertilizer and the salicylic acid plant growth regulator in the weeds control and components of soybean crop ...

Castor bean plants are susceptible to aluminum (Al) in the soil, requiring adequate management techniques for their cultivation in acid soils containing high Al levels, as it occurs in tropical regions. This study aimed ...

Guar (Cyamopsis tetragonoloba L.) is commonly grown in arid lands, because of its high drought-tolerance. However, soil compaction may be a limiting factor to its growth. This study aimed to evaluate the guar growth, ...

Nitrogen (N) anticipation in cover crops, besides increasing the accumulation of dry weight and nutrients, may favor the subsequent crop by increasing the availability of N. However, N can alter the decomposition of ...

Millet is a species of the grass family used in cattle pastures, for hay, for silage, and in soil cover in notillage systems. However, studies on seed production and post-harvest techniques for this species have not been ...

The objective of this work was to evaluate the growth, relative chlorophyll index and nitrogen concentrations in leaves, and the grain yield of arabica coffee (Coffea arabica) fertilized with rates of N as coated and ...

Seed treatment is a process that helps to control insects and soil-borne pathogens, besides allowing a given crop to reach its maximum production potential and protect its seedlings. This study aimed to evaluate the ...
